ning-Lathes, of which the following is a speci-' fication, referencebeing had therein to the accompanying drawings. 7

My invention relates to new and useful improvements in attachments forspinninglathes, and refers more especially to adevice for automaticallyperforming a spinning operation and at the same time to operate thespinning-rolls so that they will have substantially the same effectduring the spinning op.- eration' as swaging-dies.

It is the object of my invention, among other things, to construct adevice in which the spinning-rolls can be fed either-automatically or byhand and during said feeding operation actuate the spinning-rolls sothat they will impart a continual succession of hammering blows, as wellas to construct the device of few parts so designed as to beeconomically constructed and readily attached to a spinning-lathe.

To these and other ends my invention consists in the attachment forspinninglathes having certain details of construction and combination ofparts, as will be hereinafter described, and more particularly pointedout in the claims.

Referring to the drawings,.in which like numerals of reference designatelike parts in the several figures, Figure 1 is a fragmentary plan viewof a spinning-lathe with my improved attachment aifixed thereto. Fig. 2is a sectional end elevation thereof. Fig. 3 is a detailed elevation ofthe crank-plate. Fig. 4: is a fragmentaryview of the upper portion ofone of the roll-slides. Fig. 5 is a sectional plan view thereof uponline A B of Fig. 1. Fig. 6 is a fragmentary sectional view of thespindles. Fig. 7 is a fragmentary view of the slide-table, one of theslides, and adjacent mechanism; and Fig. 8 is an end elevation of SerialNo. 168,482. (No model.)

one of .the spindle-heads withthe bed in section upon line A B of'Fig.1.

The spinning-lathe shown in the drawings is especially designed forspinning collar-buttons, although of course my invention can be appliedto any other form of spinning-lathe;

but for purposes of illustration 1 have adopt ed this special type ofspinning-lathe. 7

- In spinning small devices, such as collarbuttons, the diameter of thestock is so small that itsspeed of movement is practically nothing andthe spinning-rolls havea tendency to drag upon the periphery of thestock and practically nullify their spinning action, and wherethe'device is plated with gold or silver prior to the spinning operationthe dragging of the rolls upon the stock tears the plating off, and thusproduces an imperfect product. I overcome these objections byconstructing the mechanism'so thatthe spinning-rolls strike successiveblows upon the device being spun during the spinning operation. Thisreduces the time required to perform the spinning operation, it takingmuch less time to perform a spinning operation where the rolls strikecontinued successive blows than when the rolls are held continuouslyagainst the surface to be spun, and, again, this action is such that therolls do not drag, and hence the plat ing is not torn ofi.

The spinning-lathe shown in the drawings comprises a bed 1, that issupported by legs 2 above a tray3, which tray is designed to catchchips, drippings of oil, &c. Upon the bed 1 are the spindle-heads 4: and4. Within the head 4: is rotatable the spindle 5, upon the forward endof which is a chuck 6, which is provided with a head portion 7 having aplurality of slots 8 therethrough. Within this spindle and chuck theplug 9 is movable endwise, and connected with said plug by the pintle 10is the annular grooved collar 11, which is slidable upon said. spindle5. The

collar 11 is movable lengthwise upon the spindle 5 by the yoke 12, thatis provided with rollers 13, which enter the annular groove in saidcollar, as shown in Fig. 1, and is fixed on Fig. 8.)

the pintle 12' between the ears 14 14. (See The yoke 12 is operatedthrough the lever 15, which is fixed on said pintle 12. To secure thebutton (which is designated 16 in the drawings) to the spindle 5, whichis rotated by means of a belt upon the cone 17, the jaws of the chuck 6are opened by moving the plug 9 rearwardly, through the hand-lever andmechanism above described, and then placing the button upon the end ofsaid chuck, as shown in Fig. 6. The direction of the handlever 15 isthen reversed, and the engagement of the end of the plug 9 with theinterior of the head 7 of the plug 6 expands the springfingers on saidchuck, which engage the collar-button and hold it rigidly. A slot 18through the spindle 5 is provided to permit the pin 10 to move endwisetherein.

Mounted within the head 4 is the spindle 19, which is rotated by a beltupon the conepulley 20, connected with said spindle and movable endwiseby any desired means, the details of which are not material to myinvention. Within the forward end of said spindle 19 is threaded thehead-block 21. After the button has been secured to the chuck 7, asabove described, the spindle 19 is moved endwise and the head of thebutton enters the recess in the head of the block 21, thus supporting itduring the spinning operation.

As before stated, the details of construction and type of spinning-latheis immaterial to my invention, as I can use any form or type as well asthe one herein shown and described. The spinning-rolls are designated22, the contour of which can be of any preferred form. They arerotatably mounted on studs 23, that are secured within the roll-slides24 and 25 and are vertically adjustable within the slots 26. Theseslides are movable upon the table 27 which is provided upon its underside with a tongue 28, which enters a longitudinal groove in the top ofthe bed 1 and is secured to said bed by the bolt 29, which is threadedinto said table.

The mechanism for operating the roll-slides comprises a shaft 30, whichis rotatable at one end within the journal upon the end of the table27and at the other end in a bracket 31, which is secured to the bed 1 byany preferred means. Fixed upon said shaft is a pulley 32, which isdriven by means of a belt connecting said pulley with the small portionof the cone 20. Mounted upon said shaft is the lever 33, having a handle34 at one end and a cam-roll 35 secured thereto upon the stud 36. Uponthe opposite end of said lever 33 to that of the handle 34 is rotatablysecured the crank-plate 37, provided with teeth 38 in its periphery andhaving a stud 39 connected therewith, which is journaled within the hub40 upon the end of said lever, said crank-plate being held againstendwise movement in said hub by the nut 41. WVithin the face of thecrank-plate 37 is a T-slot 42, within which is adjustably secured thestud -13, having a T-head. Mounted bet\\'een the ears 11 upon the table27 and upon the piutle is the rock-lever 46, which is connected with thestud 43 by means of the link 47. (onnecting the rock-lever 46 with theslide 2-1- is the link 48, and connecting the slide 25 with the saidrock-lever is the link 49, which passes through a slot in the slide 24and is pivotally secured at its forward end to a. bolt 50, threaded intosaid slide. The position of the stud 43 in the slot 42 determines therocking motion that is imparted to the rock-lever 46, it being apparentthat the nearer the center of the crank plate the stud 43 is brought theless rocking motion will be imparted thereto, and vice versa, so thatthe movement of the slides 24 and 25 and the spinning-rolls can beadjusted by means of the position of the stud 43, as above described.This adjustn'ient is obtained by simply unloosening the nut 51 andshifting the position of the stud within said slot and after thisposition has been secured again tightening the nut 51.

To adjust the relative position of the spinning-rolls 22 laterally, Ihave provided an eccentric-stud connection between the link .46 and theslide 24, which is illustrated in Fig. 5, the eccentric stud beingdesignated 52 and the eccentric portion thereof being within the end ofthe link 48. From this view it is apparent that by rotating the stud 52upon its axis the endwise position of the roll 22 will be varied, as theconnection between the link 48 and the rock-lever 46 is fixed.

Upon the end of the shaft 36 is the worm 53, which meshes into theworm-wheel 54, which is fixed to shaft 55, journaled in the bracket 56,which is secured to the bracket 31. Upon the lower end of the shaft isthe bevel-gear 57, which meshes into a bevel-gear 58 upon the end of theshaft 59, which is journaled at one end in the bracket 31. and at theother end in the table 27. Loosely mounted upon said shaft 59 is a cam60, upon one side of which is a hub 61, having a plurality of teeth uponthe face thereof, as shown in l i 1, and fixed to said shaft, butslidable thereon, is the clutch-collar 62, which is provided with anannular groove therein and has teeth in its front face which correspondin number and size with those in the hub 61. The engagement of thecollar 62 with that of the hub 61 makes a rigid connection between theshaft 59 and the cam 60, so that when said teeth are engaged with eachother the cam will retate and when disengaged will be at rest. Themechanism for shifting the endwise position of the collar 62 upon theshaft comprises a yoke 63, having pins 64 therein, which enter annulargrooves in the collar 62 and which is fixed upon one end of a rock-shaft65,

rec

which is journaled in the bracket66, secured to the bed 1 .A rockingmotion .is impartedto the shaft 65 through the link 67, which isconnected at one end with the bottom end of lever 65, it-being apparentthat when the lever isoscillated upon its pivot-mounting a rockingmovement will be imparted to the.

shaft 65, and through the yoke 63 an end-wise I movement will beimparted to the collar 62..

The cam-roll 3.5 is always held in engagement with the periphery of thecam 60 by move-' ment of the spring 69, which is fixed at one end to thelever 33 and at the other end to the table 27.

- The operation of my invention is as follows: The same movement whichoperates the chuck 6 so that it holds the collar 16 in engagementtherewith also causes the endwise movement of the collar 62, both beingoperated from the hand-lever 15, which engagement causes the cam 60 torotate, and during said rotation the.

engagementof thecam-roll with said cam.

causes the lever 33 to swing upon the shaft,

. 30, and through the link 47 the rock-lever 46 the roll sli'des 24 and25 are moved upon the table 27 toward each other, and through thepinion-7 0,. which is fixed to the. shaft 30 and meshes into the teeth38 of the crank-plate 37,- a rotary movement is imparted to said.crank-plate and during the movement of said slides imparts a minorGDCIYVISGbflCkWflI'drflHd".

forward movement to said slides upon the table 27 and through saidslides to said rolls 22,, the movement of the rolls then imparting a.

succession of hammering blowswhile the rolls are being fed together.After the rolls have of the slides 24 and 25 is determined by the bolt71, which is threaded into the slide 25 and moves through a lug 72 uponthe table 27. and is provided upon its outer end with the chucknuts 73.

There are many minor changes and alterations that can be made within myinvention aside from those herein shown and suggested, and I wouldtherefore have it understood that I do not limit myselfto the exactconstruction herein shown and described, but claim all that falls fairlywithin the spirit and scope of my invention.
